Spencerio?s Mod Mod 1.7.2/1.6.4

The point of Spencerio’s Mod Mod is to add in some really cool stuff which sounds challenging to players, but whose rewards are awesome.

Because the main purpose of the mod is to make Minecraft more rewarding again, you can hope to get many precious rewards such as Customizable and Boss Spawners, whose recipes are extraordinarily expensive, but allow you to spawn any mob in the game.
Currently, this mod introduces many interesting things listed below:

Many new types of dungeon, a Help Block and Help Block GUI, few flowers and so on

Perhaps the best stuff added is the Customizable Spawner and Boss Spawner. Through them, you can spawn Giants from long-lost Minecraft with the Customizable Spawner; and spawn the bosses using the Boss Spawner

Open the forge installer with Java TM SE Platform Binary. Make sure you open it with Java. (if your icon for the .jar file is the java logo, double-click it.)

Download the mod

Go to start menu, then type %appdata%, click on Roaming, go into .minecraft, and open your mods folder (if you don’t have a mods folder in .minecraft, make one, and be sure that the folder ?mods? doesn’t have ANY caps in its name).
